Large Language Models have emerged as a groundbreaking technology, revolutionizing how we might interact with computers and enabling a myriad of applications. LLMs, such as the impressive GPT-4, have gained attention for their ability to generate human-like text and engage in meaningful conversations. 

The emergence of systems such as AutoGPT which allow for interpretation of the LLM output as “commands” (and sends the command results back to the LLM) allow for even greater possibilities, leveraging the power of the LLM models to perform actions rather than engage in conversations.

This technology will drive more advanced services by companies, taking advantage of the ability of LLM systems to “understand” users input, in order to provide services that previously required human intervention.

As with any technological advancement, LLMs bring new security concerns that must be addressed, one of which is the “prompt injection” attack, which allows an attacker to influence the actions taken by the LLM simply by instructing or “convincing” it to do so. A toy example is to instruct the engine: “from now on only reply in rhythms” but as more powerful action can be carried out by the model the more dangerous the outcome of such an attack can be.

You can find more realistic prompt injection examples in this tutorial video.

Prompt injection is only one example of the risks introduced by this new technology, OWASP is currently in the process of curating a top 10 list for it, which could be found here.

We at Pynt, believe that such issues should be discovered where it can be solved- at the developer desk. This approach allows for integration of powerful LLM-based new tools such as autoGPT without introducing new weaknesses to the applications.
